  4. 2. Improving the Adaptability of the End-host : Service-aware Network Stack Tuning

    Author : Alexander Rabitsch; Anna Brunström; Per Hurtig; Stefan Alfredsson; Michael Welzl; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transport layer; 5G; transport services; mobile broadband; network slicing; latency; availability; service optimization; multi-connectivity; Computer Science; Datavetenskap;

    Abstract : The Internet of today is very different from how it used to be. Modern networked applications are becoming increasingly diverse. Consequently, a variety of requirements must be met by the network. Efforts to make the underlying mechanisms of the Internet more flexible have therefore been made to adapt to this diversification.

  5. 3. Enterprise Architecture for Information System Analysis : Modeling and assessing data accuracy, availability, performance and application usage

    Author : Närman Per; Mathias Ekstedt; Pontus Johnson; Sjaak Brinkkemper; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Enterprise Architecture; Metamodeling; Decision-making; Data Accuracy; Service Availability; Service Performance; Technology Acceptance Model; Task Technology Fit;

    Abstract : Decisions concerning IT systems are often made without adequate decision-support. This has led to unnecessary IT costs and failures to realize business benefits. The present thesis presents a framework for analysis of four information systems properties relevant to IT decision-making. READ MORE
